Abstract

SiO2/TiO2/CuO composites have been synthesized by deposition technique using low temperature hydrolysis of TiCl4 and thermolysis of Cu(CH3CO2)2·H2O at silica A-300 surface. The properties of the samples have been explored by means of XRD, nitrogen adsorption, potentiometric titration, and photon correlation spectroscopy. As the results indicate, there are both anatase and some amount of rutile formed at CCuO = 1 wt.%. A gradual shift of the point of zero charge (from pH = 3.48 to 6.60) has been observed with increasing CuO content.
